Do you remember when it was free to call directory assistance? Some free services are making a comeback thanks to a new ad-based business model. Clark's teenager recently called old-fashioned directory assistance and was charged a $1.80 before he told her about 1-800-FREE-411. Google has also launched a free service (for business listings only) available at 1-800-GOOG-411. Meanwhile, AT&T has its own service through 1-800-YellowPages.

People sometimes gripe that the numbers they get from these free services aren't always correct. But there was a recent study that found the numbers you get from paid services are just as likely to be wrong. So why pay extra for the chance of a wrong number? Clark often turns to the Internet when he's looking for a number. He practically never looks in a phone book anymore. Remember the 1979 move The Jerk starring Steve Martin? There was a scene where the new phonebook arrives and Martin goes running for it, looks up his name and shouts, "I am somebody! I'm in the phonebook!" Pretty soon people won't know what the whole phonebook phenomenon is about. In the future there may not be any phonebooks, because the costs to print and distribute them are so high. The bottom line is that you shouldn't be paying for directory assistance when there are so many free options out there. On a related note, Clark was talking to someone who lost their cell phone just a few days ago. The person discovered that thousands of dollars in international calls had been made by the thief. Under the current law, that person is responsible for those costs. To avoid a scenario like this, call your cell phone provider and get an international calling block.
